Anyone willing to share what spring is being run on 305-350 engines. I try to get 200 closed and 400 open on our engines , but it's hard to get that much pressure without adding over .200 worth of shims. I've been running the 941 Comp springs but there too close to coil bind to suit me.Is there anything out there in a 1.260-1.290 spring that has around 200lbs@ 1.800 --400@1.400. Thanks for any replies. Bill
